  • Suspension of inorganic fillers in a polyesterpolyol and production method
    Publication number: 20070161731
    Abstract: The present invention relates to a suspension of an inorganic filler in a polyesterpolyol and the method for producing this suspension. It relates more especially to a stable suspension comprising, as liquid medium, a polyesterdiol compound and, as dispersed particles, an inorganic particulate filler at a weight concentration of between 0.8 and 8%. Such suspensions are used, for example, for producing polyurethanes such as polyurethane foams or thermoplastic polyurethanes.

  • Hydraulic binder with enhanced aging properties
    Patent number: 7074269
    Abstract: Hydraulic binders, such as cements, mortars with enhanced aging properties, are described. More particularly, hydraulic binders based on mineral silicates are described having greater aging strength, a method for making said binders and their uses and articles obtained from same. An organic compound comprising two hydrophilic functions and a hydrophobic chain such as adipic acid are added to the hydraulic binder to slow down the water uptake rate of said binder.
